Principle of small spray dryer
GY-GTGZJ-3LLaboratory spray dryerIt is the air that passes through the filter and heater, enters the air distributor at the top of the drying tower, and then spirals evenly into the drying chamber. The material liquid is pumped from the material liquid tank to the centrifugal atomizer at the top of the drying tower through a filter, causing the material liquid to spray into extremely small mist droplets. The material liquid comes into contact with hot air in parallel, and the moisture evaporates rapidly, drying it into finished products in a very short time. The finished product is discharged from the bottom of the drying tower and the cyclone separator, while the exhaust gas is discharged by the fan.

Advantages of spray drying
As long as the drying conditions remain constant, the characteristics of dried products will remain constant. The operation of spray drying is continuous. Its system can be fully automatically controlled. The spray drying system is suitable for drying heat sensitive and non heat sensitive materials. The drying raw material liquid suitable for aqueous solutions and organic solvent materials can be solution, slurry, emulsion, paste or melt, and even filter cake. The spray drying operation is very flexible

The new key. At present, the main positive electrode materials in China are lithium cobalt oxide, lithium nickel oxide, lithium iron phosphate, and ternary materials. Lithium iron phosphate has the advantages of good safety, long cycle life, good thermal stability, wide source of raw materials, and low price, but it has low tap density and poor low-temperature conductivity.
The simple preparation process of lithium iron phosphate/C cathode material: LiOH and FePO4 are added to the ball milling tank to add pure water. After ball milling, a certain amount of carbon source is added. After 3 hours of spheroidizing, the slurry is taken out and sent to the spray dryer for spray drying. Carry out spray drying at a certain inlet and outlet temperature (inlet temperature: 200-250 ℃, outlet temperature:<100 ℃). After the material is dried, it is placed in an atmosphere furnace for low-temperature calcination for 2 hours, and after high-temperature calcination for 6 hours, LiFePO4/C positive electrode material is obtained. The experiment shows that the spray drying step endows the precursor material before sintering with good sphericity, and the particle size is 20-20 μ m. Under the spray drying condition, the chemical composition of the material is relatively uniform. During calcination, there is no solid-phase change between spherical particles, and the grain production of LiFePO4/C is limited to one spherical particle. Therefore, small LiFePO4/C grains can be obtained, which are beneficial for the electrical properties of LiFePO4/C.
Spray drying is used for drying precipitated silica of white carbon black, also known as white carbon black. The expression is mostly written as mSiO2 · nH2O, which is an important reinforcement raw material for the rubber industry. Because its microstructure and aggregation form are similar to carbon black, and have similar reinforcement properties in rubber, it is called white carbon black. The production methods of white carbon black include gas-phase method and precipitation method. The gas-phase method has high purity and good performance, but the production process consumes a lot of energy, is technically difficult, and has high costs. In contrast, the precipitation method for preparing white carbon black has mature technology, simple operation, and significant cost advantages. However, during the drying and dehydration process, ultrafine particles are prone to agglomeration, which affects their performance. The research shows that spray drying can obtain white carbon black with uniform particle dispersion, high specific surface area and oil absorption value, which conforms to the matching curve of oil absorption value and specific surface area of *, and is suitable for the reinforcement of high-performance tires and color tires.
Operating procedures for electronic balance: Place the electronic balance on a stable and flat surface;
Plug in the power and turn on the switch; When starting up, there should be no heavy objects on the scale tray. After the display stabilizes, place an empty container on the scale tray, but its weight should not exceed the maximum weight. Press the peel button to return to zero; After adding the required sample, the displayed value is the sample weight; After weighing, set the balance to zero first, then turn off the switch and unplug the power supply; Clean the balance with a dry cloth or brush and place it back in its original position (avoid contact with water);
The balance should be calibrated frequently using the provided weights; An appropriate amount of desiccant (such as silica gel) should be placed inside the balance. Operating procedures for portable high-pressure steam sterilizer Operating procedures for stacking: Wrap the items to be disinfected and place them in sequence on the sieve plate inside the disinfection bucket, leaving appropriate gaps between the bags to facilitate the escape of air and the penetration of steam; Add water: Add water to the sterilizer body that exceeds the height of the heating coil by 3-5cm. The water will gradually evaporate during the disinfection process, and the water level will correspondingly decrease. Therefore, after each disinfection is completed, if you continue to use it, you should add enough water again to avoid the bottom of the sterilizer body from cracking due to lack of water and being scrapped; Sealing: Place the disinfection bucket into the body of the device, and at this time, water should not flow into the disinfection bucket. Cover the disinfection bucket with a lid, and pay attention to inserting the hose into the disinfection bucket groove. The screw fastening groove of the lid should be aligned with the screw groove of the main body, and then sequentially tighten the wing nuts in the corresponding positions evenly to make the lid tightly fit with the body of the device;
Heating: Place the sterilizer on a heat source and heat it up. At the beginning, place the release valve in a vertical position to release steam. The cold air inside the sterilizer will escape through the valve hole with the heating. When the water boils and there is a strong steam shock, the release valve should be closed. The pressure inside the sterilizer increases with heating and is indicated on the pressure gauge for disinfection: when the pressure inside the sterilizer reaches the required range, adjust the heat source appropriately to maintain a constant pressure, and start calculating the disinfection time according to different items and packaging to maintain the required disinfection time; Drying: For dressings, instruments, and utensils that need to be dried after disinfection, the steam in the sterilizer can be immediately discharged through the vent valve (or safety valve) at the end of disinfection. When the pressure gauge pointer returns to zero, wait for a minute, open it, and continue heating for 5 minutes to achieve drying of the items; Cooling: If the solution and culture medium are immediately vaporized at the end of disinfection, they may boil violently due to a sudden decrease in pressure, causing serious accidents such as bottle bursting or solution overflow. Therefore, steaming should not be immediately released at the end of disinfection. The heat source should be extinguished first, or moved away from the heat source to allow it to cool naturally. Generally, after 20-30 minutes, the pressure inside the pot will drop to zero due to cooling
